send value via url in javascript

[thegenious]

hello everybody,

i got a problem to send some value via url in javascript's onload event. i have explained my problem belowl:

i.e

if some one open my site for any purpose, i want to execute a script on window.onLoad event to get info. of that computer such as OS name, browser name, etc. and want to send these value via url on another page.

i.e "http://www.mysite.com/visitors.php?os=osname&browser=browsername"

here, visitors.php is a php page where i want to send values where these values are saved into mysql database. when this process is completed. it returns some values to the main page where another process is done based on the returned value.

i want code somewhat like this:

var a="http://www.mysite.com/visitors.php?os=osname&browser=browsername"

code must be in javascript because i want to write this code in .js library.

if some one have a helpful solution pls write me.
thx in advance.

IT sounds unnecessarily complicated to use javascript to sniff out the browser and OS when you can just check the value of $_SERVER['HTTP_USER_AGENT'] or the function [man]get_browser[/man]
